The effect of massage on the plantar flexor muscles during the fixation period in postoperative patients with an ankle fracture.

INTRODUCTION: Ankle fractures are one of the most common lower extremity fractures. After surgery, the ankle joint is often immobilized in a plantar flexion position, and there have been many reported cases of limited ankle joint range of motion. Therefore, the purpose of the present study was to investigate the effect of regular massage interventions on ankle joint range of motion after removal of fixation. METHODS: The massage group comprised 30 patients who had sustained an ankle fracture and had undergone surgical fixation, physical therapy, and massage between November 2020 and March 2022. These subjects received a 3-min massage twice daily, five times a week. The control group consisted of 38 patients who had sustained an ankle fracture between January 2015 and September 2020 and had undergone surgical fixation as well as regular physical therapy. RESULTS: The respective ankle dorsiflexion and plantarflexion ranges of motion after cast removal were 2.50 ± 7.2° and 42.3 ± 7.2° in the massage group and -8.62 ± 2.9° and 34.8 ± 8.3° in the control group. An unpaired t-test showed that the ankle dorsiflexion and plantarflexion ranges of motion in the massage group were significantly greater than those in the control group (p = 0.036 and p < 0.01). CONCLUSIONS: Our results indicate that regular 3-min massage interventions of the plantar flexors could prevent the progression of a range of motion limitations in postoperative patients with an ankle fracture more effectively than regular physical therapy alone.

The acute effect of roller massager on knee joint range of motion and muscle pain in older adults with total knee arthroplasty.

OBJECTIVES: Older adults with total knee arthroplasty (TKA) have a limited range of knee joint motion due to pain and stiffness. A roller massager (RM) has recently been suggested to decrease pain and increase joint range of motion (ROM). Therefore, this study aimed to investigate the acute effect of RM intervention on pain and knee joint ROM in older adults with TKA in the second postoperative week. METHODS: The participants were 23 patients (76.3±5.4 years) who had undergone TKA for knee OA. The degree of pain during the ROM measurements was measured using the visual analog scale before and immediately after the RM intervention. The RM intervention was performed on the thigh's lateral, central, and medial parts for three sets of 60 s using an RM. RESULTS: RM intervention could significantly increase knee flexion ROM (p<0.01, d=0.41, Δchange: 4.1±3.2°) and decrease pain during the knee ROM measurements (p<0.01, d=-0.53, Δchange: -11.9±21.0). CONCLUSIONS: The three sets of 60-s RM intervention significantly increased knee flexion ROM and reduced pain in older adults with TKA in the second postoperative week. These results show that RM intervention is an effective tool for treating stiffness and pain after TKA.

A 1-Week Comprehensive Foam Rolling Intervention Program Can Improve Knee Pain but Not Muscle Function and Range of Motion in Patients with Total Knee Arthroplasty.

We investigate the effect of a 1-week comprehensive foam rolling (FR) intervention program on knee pain, range of motion (ROM), and muscle function in patients with TKA.Thirty patients with TKA were randomly allocated to FR (n = 15) or control (n = 15) groups. The control group received only regular physical therapy. Patients in the FR group performed the FR intervention in addition to their regular physical therapy twice daily from postoperative weeks two to three (60 s × 3 repetitions × 2 times/day × 6 days: total = 2160 s). Pain score, knee flexion and extension ROM, muscle strength, walking function, and balance function were measured before and after the FR intervention. From the second to third postoperative weeks, there were significant improvements in all variables, and the reduction in pain score at stretching was significantly greater in the FR group (-26.0 ± 1.4; p < 0.05) than in the control group (-12.5 ± 1.9). However, there was no significant difference in changes in the other variables except for the pain score at stretching between FR and control groups. A 1-week comprehensive FR intervention program in patients with TKA could reduce pain scores at stretching without a synergistic effect on physical function, i.e., walking speed, balance function, and muscle strength of the knee extensors muscles.
